Abstract

Landfill Gas (LFG) has been identified as a major source of contamination of groundwater underlying landfills. Contaminants consist primarily of volatile organic compounds (VOCs) such as methylene chloride, trichloroethene, and tetrachloroethene. Three mechanisms for vapor phase VOC migration from a landfill to groundwater are predominant. These are: (1) Direct contact of landfill gas containing VOCs with groundwater, (2) Vapor phase VOC migration through the unsaturated zone surrounding a landfill, and (3) LFG Condensate water formation in the unsaturated zone and subsequent migration to groundwater. Current LFG collection practices are not geared towards controlling the potential for groundwater contamination caused by LFG. By not recognizing this major source of contamination, landfill operators are missing a major opportunity to reduce costs and minimize future liability of future groundwater impacts. Existing or future LFG collection systems can be upgraded, augmented with unsaturated zone remediation, or collection system operations modified to significantly reduce the potential for VOC contamination of groundwater.

Implementation of Enhanced Attenuation at the DOE Mound Site OU-1 Landfill: Accelerating Progress and Reducing Costs - 16270

Conference Hooten, Gwendolyn; Cato, Rebecca; Riha, Brian; ...

A field demonstration of enhanced attenuation (EA) was initiated in 2014 to expedite the remediation of industrial solvents in the groundwater impacted by the former landfill Operable Unit 1 (OU-1) at the US Department of Energy (DOE) Mound, Ohio, Site. EA uses active engineering solutions to alter the target site so that the contaminant plume will passively stabilize and shrink. For OU-1, the EA was implemented by targeted injection of an electron donor (vegetable oil) to create 'structured geochemical zones'. Volatile organic compounds (VOCs) in the altered subsurface system encounter alternating anaerobic and aerobic environments along the plume flow path.more »« less
Progress toward cleanup of operable unit 1 groundwater at the US DOE0 Mound, Ohio, site: success of a phased-combined remedy - 15310

Conference Hooten, Gwendolyn; Cato, Rebecca; Looney, Brian; ...

Industrial solvents (primarily trichloroethene) and other volatile organic compounds (VOCs) that originated from the former solid waste landfill contaminated the groundwater in the Buried Valley Aquifer beneath the Mound, Ohio, Site. The landfill was used from 1948 to 1974 for the disposal of trash, debris, and liquid waste. In 1977, much of the waste was relocated and encapsulated onsite. The landfill site and surrounding area (Operable Unit 1 [OU-1]) occupy approximately 1.6 hectares (4 acres) in the southwestern portion of the site. The historical pathway of concern consisted of leaching of contaminants from site soils or disposed wastes down intomore »« less
2011 Mound Site Groundwater Plume Rebound Exercise and Follow-Up - 13440

Conference Hooten, Gwendolyn; Cato, Rebecca; Lupton, Greg

The Mound Site facility near Miamisburg, Ohio, opened in 1948 to support early atomic weapons programs. It grew into a research, development, and production facility performing work in support of the U.S. Department of Energy (DOE) weapons and energy programs. The plant was in operation until 1995. During the course of operation, an onsite landfill was created. The landfill was located over a finger of a buried valley aquifer, which is a sole drinking water source for much of the Miami Valley. In the 1980's, volatile organic compounds (VOCs) were discovered in groundwater at the Mound site. The site wasmore »« less
Groundwater impacts associated with landfill gas migration at municipal solid waste landfill sites

Conference Clister, W; Janechek, A; Hibbs, S

Many older municipal solid waste (MSW) landfills are unlined and subsequently have become a source of local groundwater contamination. However, the adverse impact on the groundwater quality at such sites is not necessarily limited to that caused by leachate contamination of the underlying aquifer but also may include the effects of landfill gas (LFG) migration. Absorption of certain LFG components, particularly volatile organic compounds (VOCs), may occur at offsite locations when a LFG excursion front migrates into adjacent soils. When LFG management systems are installed at such sites, this problem is often eliminated.
Whose Gas is it anyway? Differentiating the Source of a Large Soil Vapor Plume beneath Two Adjacent Waste Sites - 20487

Conference Hammond, Travis; Douglas, James

DOE contractor CH2M Hill Plateau Remediation Company is currently responsible for conducting groundwater contamination monitoring at several RCRA treatment, storage, and disposal units located on the Hanford Site in Richland, Washington State. The Nonradioactive Dangerous Waste Landfill treatment, storage, and disposal unit presents a distinct groundwater monitoring problem because of a large multi-contaminant soil vapor plume beneath it that is a likely source of low-level volatile organic compound groundwater contamination. Adjacent to Nonradioactive Dangerous Waste Landfill is the Solid Waste Landfill. Volatile organic compounds are inventory components of both the Nonradioactive Dangerous Waste Landfill and the Solid Waste Landfill. Therefore,more »« less
